| Abstract: | To Orthogonal Frequency Division Multiplexing（OFDM） System,synchronization is still the important topic which needs to study.Since the SchmidlCox synchronization algorithm can not guarantee the accuracy of the signal timing synchronization estimation,this thesis presents a method that optimizes the structure of the training sequence,and the simulation indicates that the method is effective. |
